Definitions
- Some embodiments specifically relate to portable infusion devices with at least one processor including instructions operating thereon for quantifying bolus doses. Some embodiments more specifically relate to insulin dispensing systems for recommending a new bolus dose by adjusting an original bolus dose by a certain magnitude according to one or more user parameters.
- therapeutic fluids e.g., insulin
- Diabetes mellitus is a disease of major global importance, increasing in frequency at almost epidemic rates, such that the worldwide prevalence in 2006 is 170 million people and predicted to at least double over the next 10-15 years. Diabetes is characterized by a chronically-raised blood glucose concentration (hyperglycemia) due to a relative or absolute lack of the pancreatic hormone, insulin.
- hypoglycemia a chronically-raised blood glucose concentration due to a relative or absolute lack of the pancreatic hormone, insulin.
- beta cells located in the islets of Langerhans, continuously produce and secrete insulin according to blood glucose concentrations ("BG levels”), maintaining near-constant glucose levels in the body.
- BG levels blood glucose concentrations
- TDD insulin total daily dose
- Basal insulin is delivered continuously over 24 hours and is intended to keep the BG levels within acceptable ranges between meal times and overnight.
- Bolus doses may be delivered during episodes of high BG levels (e.g., a "correction bolus” or “CB”) or, when delivered before, during or after meals to counteract carbohydrate loads (e.g., a "meal bolus” or "MB”).
- CB correction bolus
- MB meal bolus
- Conventional parameters used for determining bolus doses include without limitation at least one of the following:
- glycemic index e.g., glycemic index
- different units can be used, for example “mmol” instead of “mg/dL”.
- Conventional insulin pumps may provide bolus dose recommendations based on one or more of the above-listed parameters.
- an MB dose may be calculated by dividing the amount of carbohydrates by the CIR.
- bolus selector feature As comprising sets of grids of ranges of carbohydrate amounts and blood glucose concentrations, wherein each grid may correspond to a different combination of IS, CIR and/or TBG, according to some embodiments.
- additional grids may correspond to selected bolus doses and RI values.
- the final recommended bolus dose may be related to a value that is substantially equivalent to the selected bolus dose minus the RI.
- CGMs continuous glucose monitors
- BG trends the direction and rate of change of BG level
- the abovementioned general formula for determining a recommended bolus dose does not take into account numerous rapidly-changing parameters or physiological conditions (such as without limitation BG trends, physical activity levels (e.g ., exercise or sedentary state), illness (e.g., high temperature) or emotional stress) that may influence or otherwise substantially modify the recommended bolus dose determination.
- rapidly-changing blood-related parameters including without limitation, BG levels, ketones, PH levels or blood gases, may also influence or otherwise substantially modify the recommended bolus dose.
- the same 5U of insulin may have a substantially different effect on a person when he or she is exercising as compared to when that person is sleeping.
- BG level is one of the most important rapidly-changeable parameters
- the abovementioned formula only considers the current BG level (i.e., a discrete value) and not BG trends and other user-specific parameters, including those identified above. For example, if a high discrete BG level is measured, the formula recommends delivering a large bolus dose to bring the user's BG levels back to TBG. In situations where consecutive BG level measurements are consistently high (i.e., BG level is substantially constant), such a recommended bolus dose may be appropriate. However, if the high-measured BG is increasing or decreasing, a relatively higher or lower bolus dose may be more properly recommended.
- US2003/0060753 discloses a fluid delivery system for delivering a bolus dose of therapeutic fluid into the body of a user, the system comprising: a pump for delivering therapeutic fluid into the body; and at least one processor including instructions operating thereon, the processor being configured to: receive a current blood glucose level (CBG) of the user; receive a BG trend of the user, including a direction and/or rate of change of blood glucose level (BG) of the user; receive one or more first additional parameters relating to the user; receive one or more second additional parameters relating to the user, such as physical activity level or illness; and determine a bolus dose based on the CBG, the BG trend, the one or more first additional parameters relating to the user and the one or more second additional parameters, such that delivering the bolus dose to the user compensates for a change in
- CBG current blood glucose level
- BG blood glucose level
- a fluid delivery system as defined in appended claim 1.
- Embodiments of the invention are defined in appended claims dependent on claim 1.
- Devices, systems and methods for delivering therapeutic fluid (e.g., insulin) and determining a recommended amount based on one or more user parameters are provided herein.
- the mechanism or feature for determining a recommended bolus dose amount based on one or more user parameters may be referred to as the "bolus advisor.”
- the bolus advisor may be configured to operate within or in conjunction with a fluid dispensing system.
- the bolus advisor may be implemented in a fluid dispensing unit and, in particular, in a portable therapeutic fluid infusion pump.
- Some arrangements of the present disclosure may be directed to a method for determining a bolus dose of therapeutic fluid to be delivered to the body of a user.
- the method may include receiving a CBG of the user, receiving a BG trend of the user, receiving one or more first additional parameters relating to the user and/or determining a bolus dose based on at least one of the CBG, the BG trend and the one or more first additional parameters relating to the user, such that delivering the bolus dose to the user may compensate for a change in a BG level of the user.
- the one or more first additional parameters relating to the user may be selected from a group consisting of IS, CIR, TBG, TC and RI. In some arrangements the one or more first additional parameters relating to the user may be further selected from a group consisting of GI, fat content of a meal and fiber content of the meal.
- the CBG may be measured using a CGM and/or the BG trend may be received from a CGM.
- Some method arrangements may involve at least one of the one or more first additional parameters relating to the user, the CBG and the BG trend being received via a user interface.
- Some arrangements may also include notifying the user, for example, regarding the bolus dose and/or delivering the therapeutic fluid according to the bolus dose.
- the therapeutic fluid may be insulin.
- Some arrangements may also include delivering the therapeutic fluid according to the bolus dose.
- Some method arrangements may also include determining an initial bolus dose for the user based on at least one of the one or more first additional parameters relating to the user and the CBG and determining the bolus dose based on the initial bolus dose and the BG trend.
- the bolus dose may be less than the initial bolus dose if the BG trend is decreasing, greater than the initial bolus dose if the BG trend is increasing and/or substantially equal the initial bolus dose if the BG level of the user is substantially constant.
- increasing may include moderate increasing (e.g ., going up) or steep increasing ( e.g., quickly rising).
- Decreasing may include moderate decreasing ( e.g., going down) or steep decreasing ( e.g ., falling quickly).
- delivering the bolus dose to the user may compensate for a rate of the change in the BG level of the user.
- methods for determining a bolus dose of therapeutic fluid to be delivered to the body of a user may include determining an initial bolus dose based on at least one of the one or more first additional parameters relating to the user and the CBG and/or determining the bolus dose based on the initial bolus dose and one or more multiplier values. Some arrangements may involve determining the bolus dose by multiplying the initial bolus dose by the one or more multiplier values.
- the one or more multiplier values may be greater than 1 when the BG trend is increasing, less than 1 when the BG trend is decreasing and/or substantially equal to 1 when the BG level is substantially constant.
- Some method arrangements may further include retrieving, from a memory, one or more multiplier values correlating to the BG trend.
- the one or more multiplier values may be determined based on a mathematical function that correlates the BG trend with the one or more multiplier values, according to some arrangements.
- Arrangements of the methods may include any of the features described in the present disclosure, including without limitation any one or more of the methods and systems, as well as any one or more of the above and/or following features.
- the methods may include averaging a plurality of the one or more multiplier values, wherein at least one of the one or more multiplier values correlates to the BG trend and determining the bolus dose includes determining the bolus dose based on the initial bolus dose and the average of the plurality of the one or more multiplier values.
- Some method arrangements for determining the bolus dose may also include determining an initial bolus dose based on at least one of the one or more first additional parameters relating to the user and the CBG and determining a bolus dose based on the initial bolus dose and one or more absolute values.
- determining the bolus dose may include adding or subtracting the one or more absolute values to or from the initial bolus dose.
- the one or more absolute values may be added when the BG trend is increasing, subtracted when the BG trend is decreasing and/or substantially equal to 0 when the BG level is substantially constant.
- methods may include retrieving, from a memory, one or more absolute values corresponding to the BG trend.
- the one or more absolute values may also be determined based on a mathematical function that correlates the BG trend with the one or more absolute values, according to some arrangements.
- Arrangements of the methods may include any of the features described in the present disclosure, including without limitation any one or more of the methods and systems, as well as any one or more of the above and/or following features.
- Some method arrangements for determining a bolus dose of therapeutic fluid to be delivered to the body of a user may further be directed to receiving one or more second additional parameters relating to the user, where the one or more second additional parameters may be selected from the group consisting of physical activity level, emotional stress level, blood ketones level and/or trend, blood pH level and/or trend, presence of an illness and/or menstruation and body temperature.
- Such method arrangements may also include determining a bolus dose that compensates for a change in the BG level of the user and/or the one or more second additional parameters relating to the user.

- the bolus advisor 10 may adjust the bolus timing (i.e., the point in time at which bolus dose delivery is initiated) and/or duration (i.e., the distribution over time of the bolus dose) based on one or more of the following parameters: IS, CIR, TBG, CBG, BG trend, TC, GI, fat content of the meal, RI, physical activity level, emotional stress level, blood ketones level and/or trend, blood pH level and/or trend, presence of an illness and/or menstruation or body temperature.
- the bolus timing i.e., the point in time at which bolus dose delivery is initiated
- duration i.e., the distribution over time of the bolus dose
- the bolus advisor 10 may control the dispensing unit 1010 to prolong the delivery time duration of the bolus dose, shorten the delivery time duration, delay the delivery or distribute the delivery dose unequally across the delivery time duration.
- the bolus advisor 10 may determine a bolus dose according to a known formula or a bolus selector feature and determine the delivery timing and/or duration based, at least in part, on the BG trend.
- the bolus advisor 10 may determine (and/or recommend) to delay the delivery of a meal bolus dose if the CBG is low and the BG trend indicates that the BG level is rising. In some embodiments, the bolus advisor 10 may determine (and/or recommend) to shorten the delivery duration of a bolus dose (e.g., a correction bolus or a meal bolus) if the CBG is high and the BG trend indicates that the BG level is increasing.
- a bolus dose e.g., a correction bolus or a meal bolus
- the bolus advisor 10 may determine (and/or recommend) to distribute a meal bolus dose unequally if the CBG is normal and the BG trend is increasing, to first counteract both the rising BG level and the meal TC and later to counteract only the TC (depending on the contents of the meal, for example).
- FIG. 5 is an example of a flow diagram depicting a procedure, according to some embodiments of the present disclosure, for deriving a recommended bolus dose using the bolus advisor 10.
- the recommended bolus dose may depend on a single additional parameter, such as a user's physical activity level, as shown in FIG. 5 .
- a user's IS, CIR, TBG, CBG, TC and RI values are provided to calculate an initial bolus dose in accordance with a known formula or a bolus selector feature.
- the formula used in the exemplary procedure in FIG. 5 is shown at step 501.
- an initial bolus dose of 2.5U is calculated based on the provided user parameters (i.e., IS, CIR, TBG, CBG, TC and RI) and the chosen formula.
- a physical activity level parameter is inputted by the user, e.g., a "High" physical activity level designation.
- this physical activity level parameter may be correlated by the bolus advisor with a multiplier value (MV).
- MV multiplier value
- a value of 0.5 may correlate to the given physical activity level designation of "High.”
- the bolus advisor may have assigned an MV of 0.8, for example, to the parameter.
- a recommended bolus dose is calculated and output by the bolus advisor.
- the recommended bolus dose may equal the multiplier value (MV) multiplied against the initial bolus dose from step 501, i.e. a bolus dose of 1.25U (0.5*2.5).
- user parameters may be assigned an absolute value ("AV") of a bolus dose that may be added or subtracted from the initial bolus dose.
- AV may be a constant value.
- the AV may be correlated to and/or dependent upon other parameters, such as for example CBG, TBG, and BG trend.
- the AV and/or MV may be also dependent on time (i.e., vary with time) according to a predetermined pattern or mathematical function, or correlated to at least one parameter.
- one or more parameters may be assigned an absolute value (AV) of an initial bolus dose and one or more parameters may be assigned a multiplier value (MV).
- a BG trend parameter may be assigned an absolute value (AV) and added to the initial bolus dose and a physical activity level parameter may be assigned a multiplier value (MV) and multiplied against the remainder of the formula as shown below to derive a recommended bolus dose:
- AV absolute value
- MV multiplier value
- each BG trend vector may be represented by a certain multiplier value (MV).
- the absolute value of the AV parameter may be subtracted from the original bolus dose (as less insulin is required). In some arrangements, if a BG trend parameter is up, the AV may be added (as more insulin is required). In some embodiments, if a BG trend is constant (i.e., no change in blood glucose concentration), the AV will be 0.
- Arrangements of the present disclosure may recommend a bolus dose by adding and/or subtracting the AV of a BG trend to and/or from, respectively, the initial bolus dose amount provided by a user's estimation of TC or by a known formula.
- a recommended bolus dose may then be derived based on one or more additional parameters input into the dispensing unit 1010 and/or system 1000 by the user by assigning an absolute value (AV) to each additional parameter to correlate each parameter to a relative magnitude. Accordingly, the recommended bolus dose may be determined by adding or subtracting these AV's from the original bolus dose.
- AV absolute value
- a recommended bolus dose may be calculated using one or more of the abovementioned parameters and associated AVs.
- the "Original Bolus Dose" in the formula represents the bolus dose as provided by a known formula, for example.
- each parameter may influence the recommended bolus dose differently, so that a weighted average of AV may be provided rather than a simple mean.
